My father works with special needs students. This week, they are build their own pinball machine. Looking online trying to spice up the design, I found this great site with pinball designs:

Way wayyyy down belowe are what I found to be 3 Solidworks files: A loop da loop, a vertical loop and a bracket for wire tracks. This would be amazing for the children, but I can't find a way to convert these to a nice STL for 3d printing without Solidworks, which I don't own. Would there be someone willing to convert these? I have attached them in a ZIP file. Pinball

Thanks in advance!
